' Application filed in, iam. flurlpllo. zs'msaa. (No man)" To all whom idmay concern:- Be it 'known" that I, HARRY D. Humans LEY, of Bristol, Bucks county, and State of Pennsylvania, have invented an Improvement' in Bag-Filling Machines, of which the following is a specification. My invention has reference to bag-fillingmachines; and it consists in certain improve,-

. ment-s, all of which are fullyset forth in the following specification, and shown in the accompanying drawings, which form part thereof. v

The object of myinvention is to automatically fill paper bags wit-h seeds or other material, substance, or articles, and seal the same after being .filled or charged with its predetermined contents. Thesefunctions are 10 is a plauview of same.

fiFig. 12 isa cross-section of bag with filling- 1'40 nozzle in it on line 10 w on Fig. 9, and Fig. 13 represents various views of the bags in the A is the bed-plate of the machine. B B are two band-wheels supported therein and adapted to feed the endless band C. The band is keptitaut by the adjustable bearings C? for one 9 f the wheels B and runs in front of a supporting-frame, R. The band C is pro-- vided with projections D, secured to it at inter- V8-1B apart to catch and feed the bag through the machine, and is a traveling feed for the bags. a v

Referring, first, to the. construction shown in Figs. 1 and 2, the bag isplaced upon the guide L, made adjustable vertically for different-sized by means of the slotted brackets l and bolts 1'. This guide L is the support for the bags while they are being fed. The bag is then pushed forward by "the projections D, its body port-ion passing back of the guide F andlying next to the band C,

and its flap is pressed slightly hack in entering'and is held back by passing under the guide G. (See Figs. 1 and 3.) The hoppernozzle H, being down to fill a previously-inserted bag, is lifted by the projection D striking the edge J of lever J, which is pivoted at j. The hopper-nozzle is thus raised to the position shown in Fig -1, and remains in that position so long as the projection D is under the edgeJ of lever J. The hopper-nozzle H is made oblong in cross-section, and is shaped as shown in Figs. 5 and 6. It is hollow, and

has lateral openings h in,the line of' the travel of the bag for the passage of the seed into thebag. The upper part of the nozzle isfui'nished with a hopper, H, and the opening from the hopper into the nozzle is closed by a valve,'H which remains closed by its own weight when the'nozzleis raised, and isopened'by the descent of the nozzle through the agency of the cord H, which is attached at one end to the valve or its stem and at the other end'io the standaitl'Ill.v The hopper and nozzle are provided with lateral guide-pins h, which move in guides l I I in frames 1 These guides are provided with switoliesz'and i to insure the pins h following the vertical guide I in descending, then-to travel in the guide I with the bag, and finally to rise up-outof' the bag and return by way of guide P .to the top ofguide I again. The

' guide I allows the nozzle to travel for a short period of time with the bag to insure its contents being transferred to the bag. A. spring, h, (see Fig. 2,) holds the nozzle toward the band and toward the flap, Fig. 6, to insure the nozzle entering the bag; The lever J has slots J, through which the. pins h pass, and

whereby the movements of said lever cause the nozzle to riseor fall. As the projection D passes from under; the-edge J 2 of lever J, the ulever falls and allows the nozzle-II to quickly 'descend," enterin g the bag, which is then under itiin position to receive the seed. The flap of the bag is just passing from' under the guide G-and' is resting-on the guide ,Fig. 6. Prior -to descending, the hopper H as received its.

charge of seed to fill a single bag. from any automatic measuring device or by hand, and as the nozzle falls and descends to the bottom of the bagtheslack cord II is taken up and the valve'vH is lifted, allowin'g the seed "to he! discharged'into the bag. The bag'then-moves on with the nozzle, andthe nozzle is] then withdrawn by the next projection D acting upon the lever J. -Dui,'ing theseoperations "the bagwas held againstlthe band (1- by the guides f E"? At place of fillin'g the positive guide f is bent out, as shown at: f, to allow easy descent of the nozzle. The lower edge of the bag while being filled wash'eld back against the band by guide L; The bag new passes under guides. K which are pressed ward the b'andby springs k,-'Figs. '1', 2, and 3.

The flap is then folded down by the ifolder M, which may be of any suitableconstructionrand a curved metal plate, M extending out.

such as is used in manypaper-bag inachines though the construction I prefer is that shown in Figs. 1 and 4, which consists of aformer, M,

fromand; partially surrounding-the former M'. 7 Between this former M -aiid :the metal plate M the flap of the bag passes when itis being folded. 'After. being bent down the flap is pressed up slightly by the extensionm of,thecurved plate M Figs. -1 and 2, son's to pass over the pastewheel Nto'applypaste to its undersurface. The aste-wheel is madeiof a wheel, N, having a knife-edged pe 'riphery and set at 'an incline,- which receives paste from a wheel, .N' running in a pastebox, Nf. Any form of pastingdevice'may he used 'and may-be driven in any of the wellknqwn ways found upon paper-hag machines. After receiving paste the fl'aplis pressed down by guide 0, and .then runs under the 'press-' 'urea'ollers P, pressed against :the' flap by pasted or'sealedsprings p. 3 The filledandbag'isthen discharged at Q.

at one end of the bandC, and the bags are placed therein and forced up against the guide L at the bottom and guide G at the top by a follower or feed-plate, S, pressed up by springs 8 or, otherwise This 'constitutcsa magazine-feed. 'lhe prcssure causes the mouth of the bag to be slightly opened, as

shown'in Fig. '11, to receive the nozzle. The nozzle II is hinged, to a sliding frame, J, by

links 'J.,' This frame J* has hinged dog J, which hangs down so as to be caught by the projections DonbandC. 'lhe'frame J slides horizontally upona stationary guide-frame, S

1?,whicli has theilower horizontal guide, I, the oblique upward guide, I with the switch "i' at the top return-guidelfl and'vertical guide I. 'The pin or roller 71 on the nozzle II runs upon these guides, as in the case first described. The dog J has a pin which runsagainst th'e'uuder edge of the frame I,

and the vendvof said frame trips said dog when it runs oif the end i thereof. The operation would be. as follows: The nozzle having entered the bag and discharged its seed, the

projection-1D on the band C strikes the dog J and'pulls the frame J with it. This action draws the bagwith the nozzle in the direction of the arrow, Fig. 9, until in position tohe ,caii'ght bythe next projection 1). Further movement-offlfiiame Jcauses-t-hc pin/7: to run up the guide 1 above switch -i'. The bag is then filled 'andfree topasson. to the folding and pasting devices.
